HP Compaq nc 8230, XP Pro SP3
Hadn't used the laptop for awhile, had black screen after I charged it then tried to start it.
Disconnected the battery & held start switch for about a minute, reinstalled the battery, then the hp logo showed on startup and after a couple tries Windows booted.
Was trying to find out how to run an external monitor. Went into the control panel / display / settings, found that I had 2 options under DISPLAY, but both were identically worded - basically for multiple monitors. One was #1, the other was #2. I hooked up the external monitor and it worked fine. I tried toggling between #1 to #2 with no problem or change in what was displayed.
I shut down the laptop, then unplugged the external monitor.
When I try to restart, I have a black screen, nothing at all shows incl the hp logo that usually shows right at the start. The HDD, etc, indicator lights still show that things are running normally.
The only thing I did was leave it on the #2 display setting, altho it read identical to #1, essentially "multiple monitors"
When I got the black screen on startup after disconnecting the external monitor, I also tried the fn+f4 button which is supposed to be the multiple monitor function, without any result or change in the black screen. When I had the external monitor hooked up and working I tried that to see if it had any effect but it did not.
Appreciate any help to get the display back to functioning.
